rename MemoryError -> OutOfMemoryError

[rened]

While it is clear to the core devs what a MemoryError is and this might feel like bike-sheddding, I believe that this will considerably improve the clarity of the error message for beginners.

This can turn the user experience of "I get these random internal memory errors. Julia is so not stable yet." into "I see, not enough memory. Will try with less data then."

Had to invest a couple of hours myself, trying to debug these elusive MemoryErrors which only occured on specific machines, while the root cause was so simple and my own fault.

To be conservative, there should probably be an alias for the old name in base/deprecated.jl.

[rened]

Good point, added MemoryError to deprecated.jl

The OSX build on travis had a timeout. Is there a better way to trigger a pull request rebuild than by pushing a dummy commit like I just did?

[nalimilan]

I'm able to restart the build from the Travis webpage, but maybe you need rights to do that. If not, then you can always force-push the same commit, only updating the date: git commit --amend --date=now && git push rened +memoryerror. The commit you added fails the tests because of whitespaces...

[nalimilan]

Oh, and you can remove that commit using git rebase -i HEAD~2, and then again a force-push.

thanks for the hint!

Seems reasonable to me. @JeffBezanson, any opinion on the name change?

[JeffBezanson]

Fine by me.
